IMPROVEMENT IN ROLLING COLTERS'.

Specification forming part of Letters Patent No. 207,589, dated September 3, 1878; application filed June 14,1878.

To all whom it may concern:

-Be it known that I, ALBERT H. BURLIN GAME, of Sparta, in the county of Randolph and State of Illinois, have invented a new and useful Improvement in Rolling Golters, which improvement is fully set forth in the following specification and accompanying drawings, in

which latter- Figure l is a side elevation of my invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a horizontal section in the lines a' of Figs. l and 2. Fig. 4 is a detail view of one of the clamp-plates by means of which the colter is fastened to the plow-beam, and Fig. 5 is an illustration of the attachment of my improved colter to a plow.

The nature of my invention consists in certain constructions, combinations, and arrangements, hereinafter described and specically claimed, whereby a revolving colter-frame can be very conveniently adjusted vertically and horizontally, and rmly secured after such adjustments.

In.the drawings,-A represents a forked colter-frame, provided with suitable holes, a, at its lower ends, into which the pivot of a rolling colter is inserted. The frame A is pivoted to and between two horizontal ears, b, of a plate, B, by means of avertical pin, al. The horizontal swinging motion of the frame A around the pin al is limited on one side by a check, bl, formed on the plate B, and on the opposite side by a check, a2, formed on the upper part of the frame A, so that the frame will strike the check b1 when swinging too far to the right, and the check a2 will strike the plate B when the frame swings too far to the left. The back of the plate B is provided with transverse serrations b2, and with a longitudinal vertical slot, b3, through which latter a bolt, C, is passed, and which is also passed through a slot, d, in a plate, D. The head c of the bolt G is fitted into avertical depression, dl, of the plate D, so as to be ilush with its back.

The plate D is provided with serrations d2, similar to those b2 of the plate B, into which serrations of plate B they lit or match whatever may be the adjustment up or down of the colter and its frame. The back of the plate D bears against the side of a plow-beam, E, to

which it is fastened by means of a diagonal clamp-plate, F, and two bolts, f f. The head of the bolt f is at d3 let into the metal of the plate D, so that the surface of the said head will be ilush with `the surface of the plate D, and thus the plate B can move freely over it when its position is to be changed. The bolt f is passed through a slot, d4, in the plate D, in order that it may be raised or lowered to accommodate the colter toplow-beams of different widths.

When the colter-frame with colter att-ached is to be applied to a plow,'the clamp-plate F is partly detached from the plate D by removing the bolt f. The plates D and F are then from below slipped over the end of the plowbeam E and the bolt f reinserted, and the plates D and F firmly clamped on the plowbeam E. The bolt C is then loosened and the plate B adjusted to the proper height, whereupon the bolt C is again tightened and the plates B and D firmly clamped together, and prevented by the serrations b2 d2 from slipping vertically upon each other, said clamp permitting the colter-frame to be adjust-ed in a horizontal direction upon the plow-beam, and in a vertical direction upon the plate D. Thus the general adjustments of the colter are greatly improved, for the reason that the vertical adjustment of the colter-frame which will sufiice for a given depth of plowing can be secured independent of any horizontal adjustment, while the longitudinal horizontal adjustment, which depends upon the condition of the soil and must be altered as often as the soil changes, can be secured independent of the vertical adjustment. n j

The bolt f', by its position below the plowbeam and nearest to the colter-frame, serves as a check against the `turnin g of the plate D on the plow-beam, it being caused to bind against the beam by the upward force of the colter while in operation.

I am aware that a swinging and verticallyadjustable rollin g-colter frame is not, broadly, new, and therefore I do not claim such as my invention; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rotary colter, the combination of the and its check a2, the serrated plate B and its plates B D, having horizontal serrations b2 d2, check b1, the serrated plate D., clamp-plate F, and the bolt C, constructed substantially as and bolts C ff', all constructed and operatshown and described. ing.;` substantially as described.

2. The combination of the swinoinfv frame A for a rotary colter, the serrated plates B D, ALBERT H BURLINGAME' clamp-plate F, and bolts C ff', substantially Witnesses: as and for the purpose set forth.

3. The combination of the eolter-frarne A I T. S. ELLIOTT, W. K. HoDsoN.
